Power Factor Correction Boost Converter Design Guide

This document serves as a technical guide for the design methodology of a Power Factor Correction (PFC) Continuous Conduction Mode (CCM) boost converter. It outlines key elements such as equations for design and power loss estimation, as well as a selection guide for semiconductor devices and passive components. The guide presents a 1200 W design example, complete with calculated and experimental results, including schematics, layout, and a bill of materials. The intended audience includes design engineers focused on CCM PFC boost converter projects. The document discusses the operational modes of the boost converter, specifically identifying the advantages of CCM over Discontinuous Conduction Mode (DCM) and Critical Conduction Mode (CrCM) in high power applications. It emphasizes the importance of selecting appropriate inductors and managing current ripple to optimize performance in various operating conditions. Overall, the guide aims to deliver practical design considerations and methodologies to enhance power factor correction in relevant applications.
